본 연구는 도로, 하천, 댐 등 시설물 건설공사를 설계하는 과정에서 생성되는 각종 보고서, 계산서, 내역서 등의 설계문서를 단순하게 전자화하지 않고 정해진 구성체계와 항목에 따라 전자화 할 수 있도록 전자문서 표준체계를 정립하고자 DTD를 개발하였다. 아울러, XML을 기반으로 설계문서를 전자문서화하기 위한 개발 절차와 방법을 마련하였으며 건설분야에 설계문서 DTD를 적용하기 위한 방안을 제시하고자 하였다.

CALS is a strategy to share integrated product data through a set of standards to achieve efficiencies in business and operational mission areas. In this paper, we studied current status for CALS standard and then analyzed the case of US DoD. The results can be summarized as implementing for two major standard in defense CALS system. They are STEP and XML. Korea Defense can be used to set direction for CALS standard implementation and standard selection process based on this paper's recommendations.

IDEF(Integrated Definition) method, a standard methodology of CALS process modelling, was applied to the weapon system R&D process to provide information modelling by analysing about goal, input, output and constraints in the R&D process. The information to be managed in R&D institutes was identified by using SmartER which is the automation program of IDEF1/1X and obtained information modelling for TO-BE model. The work process of weapon system R&D consists of the concept study phase, the exploration development phase, the system development phase, the prototype manufacturing phase, and the report writing of R&D results phase. The information modelling of weapon system R&D is the R&D work process with information sharing by means of IWSDB Since IDEF is suitable for large scale system development like weapon system R&D, further studies on IDEF would be required to achieve the goal of defense CALS.

실시간 군수정보체계 구축을 위해서는 모든 군수자산의 현황, 즉 전체 자산 가시화(Total Assets Visibility)가 이루어져야 한다. 즉, 물자가 어느 곳에 위치해 있는지(이송 중에 있는 물자 포함), 보유수량은 얼마인지, 물자의 상태는 어떤지를 한 눈에 확인/통제할 수 있는 시스템을 말한다. 또한 무기체계 연구개발, 획득, 군수품 조달 및 청구업무에 필요한 각종 정보가 공유/이용될 수 있도록 CALS체계를 구축해야 할 것이다.

CALS의 개념을 한마디로 정의하기에는 범위나 방법상 어려움이 있다. 그럼에도 불구하고 과거에는 군의 무기체계를 지원하는 개념에서 출발하였으므로 일반적으로 "무기체계의 설계, 제작 및 군수유통체계 지원을 위해 디지털기술의 통합과 정보공유를 통한 신속한 자료처리 환경 구축"으로 정의할 수 있었다. 그러나 이제는 "제품의 생산(생산계획 등 이전 활동 포함)으로 부터 폐기에 이르는 모든 활동을 디지털정보기술의 통합을 통해 구현하는 산업화전략"이라는 표현으로 바꾸어야 할 것이며, 이것은 곧 제품에 대한 요람에서 무덤까지의 총체적 관리를 위한 정보기술 통합전략이라고 정의할 수 있을 것이다.

CALS/EC is about doing business electronically. It is based on the electronic processing and transmission of data, including text, sound and video. It encompasses many diverse activities including electronic trading of goods and services, online delivery of digital content, electronic fund transfers, electronic share trading, electronic bills of lading, commercial auctions, collaborative design and engineering, online sourcing, public procuremet, direct consumer marketing, and after-sales service. It involves both products(e.g. consumer goods, specialised medical equipment) and services(e.g. information services, financial and legal services); traditional activities(e.g. healthcare, education) and new activities (e.g. virtual malls). CALS/EC will be emerging to replace and substitute the role of the conventional market. By changing and eliminating some processes of the transactions, the electronic market and the electronic commerce will redistribute the power and hence the benefits of the market activities. Traditional way of doing business may enter into the new electronic market because the role and function of trust and established reputation will be reinforced in the electronic market. The CALS/EC through the Internet has been in the spotlight in the shopping behavior of the consumers. Accordingly Corporates are trying to adapt themselves to those rapidly changing environments being affected by the Internet. Among others, particularly to be noted is the CALS/EC between corporations and consumers whose potential growth can be considered very substantial. This report, focusing on the introduction of CALS/EC for the logistics of SMEs, will allow us to prepare more efficiently for the coming 21st Century. It is obvious that CALS/EC is fast becoming the useful way of exchanging not only information but products in business between firm-to-firm and firm-to-customer.

Recent construction projects consist of large and complex facilities, which project management information system (PMIS) is used for managing construction cost and schedule. The ministry of land, transport and maritime affairs (MLTM) is using a continuous acquisition and life-cycle support (CALS) system for managing the public construction projects. This study attempts to survey some problems of the CALS system in practical application, and then suggests the new functions to improve practical application of the CALS system. All functions in each menu were analyzed in the practical application aspect. All projects ordered from MLTM should use the CALS system as a PMIS, but the practical application is limited in partial functions and special working group. And the utilization of system is focused on simple tasks and report process. One of main reason is that the system is using numerical data rather than graphical data. This study suggests new functions and a visualized management method that can improve the practical applicability using a 4D object in each current functions.

As most landscape drawings tend to be recorded in electronic format, the need for layer standards is growing. While the categorization system of planting drawings has been progressing, landscape facility drawings are being delayed. So, the purpose of this study was to establish the categorization system of computerized landscape facility drawing documents. In the beginning of this study, it found that the layer categorization system of "The Standards of Construction CALS/EC computerized drawings v1. 1" and "The submit instructions of electronic design documents" are not suitable for the landscape facility drawings. 1,154 drawings drawn by 10 landscape architect offices were used to analyze the current layer categorization status. As a result, it found that "The Standards of Construction CALS/EC computerized drawings v1. 1" were not introduced in landscape facility drawings and 46% of layers were produced indefinitely. The new layer categorization system consisting of 15 facility items was drawn by applying the ISO construction information categorization system. The new layer categorization system is set on the basis of the legal code, landscape design standards, and design guidelines of public institutions. This new layer categorization system is expected to propagate at the landscape architect offices in the early.

정보화 사회에서 개인의 프라이버시와 국가 차원의 보안의 균형있는 발전은 매우 중요한 과제이며, 1997년 3월 국제 경제개발 협력기구(OECD)는 암호기능을 적용하기 위한 정책인 ‘OECD 암호정책’을 수립하였으며, 이 지침의 특기할 점은 암호화된 데이터를 국가 등의 제 3자가 강제적으로 해독하는 것을 인정하였다는 것이다. 이러한 OECD 암호정책은 공공의 안전성 확보에 필요한 조치임과 동시에 개인 프라이버시 침해의 위험을 내포한 암호정책으로 세계를 상대로한 CALS/EC 산업에 이러한 기술이 표준화되어 적용될 가능성이 높기 때문에 향후 국내의 CALS/EC 보안 서비스 제공시 중요한 지침이 될 것이다. 본 논문에서는 CALS/EC 보안 서비스를 실현하기 위하여 연구 개발해야 할 보안 기술 중 암호문의 강제 해독 기술 및 인중 기술을 포함한 보안 프레임워크를 제안한다.
